specific Embodiment approach
[0042] A specific embodiment, the vibrating container 201 is cylindrical; its length, width and height are not particularly limited, as long as enough catalyst can be placed in the vibrating container, of course the volume and inner diameter of the vibrating container 201 are preferably within a certain range Within, if the volume and inner diameter are too small, there will be less microsphere catalysts that can be inserted, and the catalyst will wear more severely under the same vibration and wear treatment conditions, and the error will be larger; if the volume and inner diameter are too large, the wear-resistant balls and catalyst will The collision probability is reduced, prolonging the time of wear and subsequent measurement; preferably, when the wear-resistant balls are placed in the container body, if the wear-resistant balls are distributed on the bottom surface of the container body in the form of a single layer, all wear-resistant The projected area of the small ba...
Embodiment
[0052] Five kinds of catalytic cracking catalysts CRMI-2-1, CRMI-2-2, HGY-A, CRSC, CDOS samples were placed in a roasting furnace at (650±5) °C for 1 hour and cooled to room temperature. Using a Malvern 2000 laser particle size analyzer (refractive index set to 1.53, liquid phase dispersant is water) to measure the mass fraction of the 0-20 micron part of the catalyst after the above-mentioned roasting, 1-(0-20 micron part mass fraction score) as a 1 . Weigh respectively 10g of the above roasted catalyst samples and 100g of steel balls with a diameter of 5mm (the density is 7.9g / cubic centimeter), and place in such figure 1 In the shaker container shown (inner diameter of the top cover is 10.5 cm and height of 1 cm; inner diameter of the container body is 10 cm and height of 6 cm), and placed in figure 2 The vibratory abrasion treatment was performed on the vibratory platform shown. Set the vibration frequency of the vibration platform to 280 times / min, the vibration time ...
